The Oregano Oil that MH talks about has almost nothing to do with the oregano that we use in Italian cooking or salads. It comes from a wild oregano herb that grows in the mountains along the Mediteranean sea and is very concentrated and powerful. One drop in a gallon of water will make the whole gallon of water taste like oregano oil. All of the wild oregano I have seen comes from Turkey, but MH says the seller is in India, so you might have some luck finding it there. If you do find the pure wild oregano oil treat it with a lot of respect and caution and don't put it on your salads. Cayenne pepper would be a cool blessing in comparison.
